Although The Big Bang Theory’s next spinoff won’t be a direct sequel series, the original show’s stars have already made mixed comments on the possibility of returning to their most iconic roles. By the time The Big Bang Theory’s series finale aired, the sitcom had cemented its status as one of the all-time great hang-out shows. Alongside Cheers, Friends, How I Met Your Mother, Seinfeld, and New Girl, The Big Bang Theory was a hit sitcom with a massive fan base who mostly tuned in to see how the quirky Pasadena gang handled personal and professional chaos.
Even Young Sheldon’s finale couldn’t recapture the popularity of the original series, and it is easy to see why. The Big Bang Theory’s cast of characters shared an easy chemistry that made them some of television’s most highly paid stars ever, and their unique interplay was impossible to replicate. Despite this, it is not clear whether The Big Bang Theory will ever receive a direct sequel series. Now that the next Big Bang Theory spinoff, Stuart Fails to Save the Universe, has been announced, there’s no better time to look back on what the cast has said.

Cuoco Told People Magazine She Would “Absolutely Reprise That Role”

Cuoco added that she loved the character of Penny and always will, saying her 12 years playing Penny on The Big Bang Theory were some of the best years of her life and some of the most fun she ever had. Cuoco was a sitcom stalwart even before she was cast, appearing in 8 Simple Rules… For Dating My Teenage Daughter before The Big Bang Theory.
Since The Big Bang Theory ended in 2019, Cuoco has gained critical acclaim for her roles in the dark comedies The Flight Attendant and Based on a True Story, as well as her lead role in Harley Quinn. The Flight Attendant and Based on a True Story lasted two seasons each, while Cuoco also appeared in 2022’s Meet Cute and 2024’s Role Play.

When Simon Helberg appeared in the season 3 finale of Night Court, he was reunited with his love interest from The Big Bang Theory, Melissa Rauch. According to Entertainment Tonight, Helberg said The Big Bang Theory cast were no longer in touch, making a future reunion seem less likely.

The Series Star Said “I Don’t Think So” When Asked In 2024
Reportedly, it was star Jim Parsons’ decision to wrap up his time as Sheldon Cooper that was instrumental in the end of The Big Bang Theory.

Entertainment Online about the possibility of a follow-up show, Parsons said “Look, never say never to anything… Life is long, God willing. But I don’t think so.”
Parsons narrated Young Sheldon and, although Young Sheldon’s spinoff Georgie & Mandy’s First Marriage hasn’t featured an appearance from the actor, this does mean he has been in close contact with the character more recently than his co-stars.
Parsons’ comments are notable since, unlike his co-stars, he had reprised the role of The Big Bang Theory’s Sheldon after the show ended. Parsons narrated Young Sheldon and, although Young Sheldon’s spinoff Georgie & Mandy’s First Marriage hasn’t featured an appearance from the actor, this does mean he has been in close contact with the character more recently than his co-stars.

Kunal Nayyar Thought 2023 Was Too Soon For A Big Bang Theory Reunion
The Actor Told TVLine “It Feels A Little Too Soon”
Speaking to TVLine back in 2023, Raj’s actor Kunal Nayyar admitted that he thought it was a little too soon for a revival of The Big Bang Theory. The star, who has since appeared alongside Rauch in an episode of Night Court, questioned whether a new season of the series would really be a revival at this stage or simply another season of the original show. However, Nayyar wasn’t averse to the idea, saying “We’ll see what the universe says” once The Big Bang Theory’s next spinoff is released.
Amy’s Actor Mayim Bialik Wants A Big Bang Theory Reunion
The Blossom Star Said She Would Be “Super Happy” To Play Her Part Again
In Jessica Radloff’s 2022 book The Big Bang Theory: The Definitive, Inside Story of the Epic Hit Series, the writer discussed the ways that Parsons’s decision to move on from The Big Bang Theory resulted in mixed feelings among the rest of the cast. This was proven in 2025 when Amy’s actor Mayim Bialik told Yahoo Entertainment that she would be delighted to reprise her role for a reunion.
Star Johnny Galecki also hasn’t commented publicly on the possibility of a follow-up show.
Bialik went on to say that she believed many viewers and creatives who worked on the show would like to see more from the main characters, with “All due respect to Jim.” This comment seems to imply that Parsons could be a major holdout among the main cast when it comes to a possible reunion. However, it is important to note that star Johnny Galecki also hasn’t commented publicly on the possibility of a follow-up show.
A Sequel To The Big Bang Theory Appears Unlikely In 2025
The Cast’s Comments Aren’t Weighted Toward A Reunion
It is not clear whether The Big Bang Theory’s sequel series will ever happen, but it is clear that there is no consensus about the show’s future among its main cast. Parsons’ reticence and Galecki’s silence are counterbalanced by Bialik and Cuoco’s shared enthusiasm, making it tough to guess whether the follow-up show could realistically happen in the near future. It is worth noting that How I Met Your Mother’s reboot, How I Met Your Father, lasted only two seasons.
As such, it might be wise to wait a little longer before rebooting The Big Bang Theory, especially with a spinoff already on the way. If Stuarts Fails to Save the Universe proves a success, this could confirm that there is plentiful fan interest in the show, which might result in a follow-up. However, as of mid-2025, the cast appear to be uncertain about the odds of a sequel series for The Big Bang Theory ever happening.
